Lexan EXL Filament

High Toughness, High Strength

Sabic has launched the new Lexan EXL AMHI240F filament. This product is based on the company’s Lexan EXL polycarbonate (PC) copolymer technology, which delivers high impact performance and low-temperature ductility.

The new filament addresses the need for higher-performing materials in the industrial sector, and is designed for use in Stratasys Fortus Classic industrial printers. It is a potential material of choice for demanding aerospace, consumer electronics and automotive applications. Lexan EXL AMHI240F filament is the first of several new materials with distinctive performance characteristics that the company plans to launch in the coming year.

The new filament features a high level of toughness, as well as improved ductility at room temperature and at temperatures down to -30°C. Compared to standard PC, this material delivers up to four times better notched Izod impact at room temperature, and up to three times better at -30°C, depending on print orientation. Lexan EXL filament has a heat deflection temperature of 140°C, which is higher than that of general-purpose acrylonitrile-butadiene-styrene (ABS) filaments. This makes the new Sabic filament a great candidate for use in applications that operate at elevated temperatures.

Lexan EXL AMHI240F filament complies with Underwriters Laboratories’ UL94 V-0 flammability standard at 3.0 mm in flat (XY) and on-edge (XZ) orientations, making it appropriate for a broad range of applications requiring fire resistance. It is available globally for sampling. It is initially offered in black, with plans to launch additional colors, including white, in the near future.
